BRAKE-BEAM.

Specification of Letters Patent.

Patented April 14, 1908.

Application filed Novenilber 15, 1907. Serial No. 402,312.

To all whom it may concern:

Be it known that I, CHARLEs H. WILLIAMS, Jr., a citizen of the United States, residing at Chicago, Cook county, Illinois, have invented a certain new and usefulImprovement in Brake-Beams, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, forming part of'this specification, in which Figure 1 is a side elevational view, partly in section, of in improved brake beam; Fig. 2 is a horizonta sectional view of one end of the beam; and Fig. 3 is a detail View of the end casting used in connection with my improved beam.

This invention relatesto a new and useful improvement in brake beams, the object being to provide means whereby brake heads of standard type which have heretofore been identified with National hollow brake beams that is, beams wherein the compression member is in the form of a tube, may be used on what is known as the Creco brake beam, that is, one wherein the compression member is in the form of a U-shaped rolled section. It is obvious, however, that other shapes or sections can be used in place of the particular section illustrated in connection with the compression member shown. By employing an end casting such as shown in Fig. 3, the recess in which the lug on the brake head fits can be so located as to give the proper throw to the head on the beam, and in this manner keep the throw in the beam structure and independent of the head.

In the drawings, 1 indicates the compression member of a brake beam, 2 the tension member, and 3 a sleeve or socket of the brake head, which sleeve or socket is provided with a closed end against which impinges the nut 4 on the tension member. The brake head is provided with a lug 5, and heretofore it was the practice where a tubular compression member Was used, to notch the tubular comchan ed without in the least changing the location of the lug in the brake head. By the means above described I am thus enabled to use the same brake head with the lug located in the same relative position on different types of brake beams.

I am aware that minor changes in the construction, arrangement and combination of the several parts of my device can be made and substituted for those herein shown and described without in the least departing from the nature and principle of my invention.

Having thus described the invention, what is claimed as new and desired to be secured by Letters Patent is:

1. The combination of a brake beam, an end casting extending over the end of said beam and having a portion that is capable of being notched at different points so as to impart different throws to the brake head, and a brake head provided with a rigid lug or projection that enters the notch in said end casting; substantially as described.

2. The combination of a brake beam, an end casting mounted on said beam and having a circular head capable of being notched at different points around its periphery, and a brake head surrounding the circular head of said casting and having a lug designed to fit in the notch in said casting; substantially as described.

3. The combination with the compression member and tension member of a brake .beam, of an end casting affording a seat for provided with a lug fitting in said notch or recess, the end wall of the socket of the brake head being closed, and 1 provided with an opening for the passage 0 the tension member, and a nut on the end of the tension member bearing against said brake head; substantially as described.

5. A casting adapted to be used on a brake beam and being so constructed that it will interlock with the compression member of said beam, said casting being provided with a notch for receiving a lug on the brake head; substantially as described.

6. A casting adapted to be used on a brake beam and having an end wall which extends over the end of the compression member of the beam and is provided with a notch for receiving 2. lug on the brake head; substantially as described.

7. A casting adapted to be used on a brake i beam and provided with an end wall which engages the end of the compression member member, said end wall being provided with a notch for receiving a lug on the brake head; substantially as described.

8. A casting adapted to be used on a brake beam and consisting of a disk-shaped portion having an integral lateral extension, said disk-shaped portion being provided with an opening for receiving the truss rod of the brake beam and a notch for receiving a lug on the brake head; substantially as described.

In testimony whereof I hereunto aifix my signature in the presence of two witnesses, this 17th day of October, 1907.
